Project Description

The Iowa Department of Transportation (DOT) worked with its research partners to design comparative pavement foundation test sections at the Central Iowa Expo Site in Boone, Iowa. The project was constructed from May through July 2012. Sixteen different 700 ft long test sections were constructed on 4.8 miles of roadway with the following goals:

Construct a test area that will allow long-term performance monitoring

Develop local experience with new stiffness measurement technologies to assist with near-term implementation

Increase the range of stabilization technologies to be considered for future pavement foundation design to optimize the pavement system
